Do I have to have an FF for a camera trap? I do not think so, a good or second-hand Crop frame is fine. I use a Nikon D7100 & a D7200 for my camera traps. These have a 24MP sensor which is more than enough in my eyes. As a lens, I use an old 18-70 mm without image stabilization. Be careful not to use image stabilization. This is also not desirable for a camera trap. Often a 10-20 mm lens is also used.
Setting up a camera trap is not easy. Your location, subject and lighting are essential for making a good photo. The better you know the animal, the better the photo becomes. Knowledge is so important with nature photography in my eyes. Both the knowledge about the animal and knowledge about your equipment is essential.
Before I install my camera somewhere I do preliminary research using game cameras. These are cameras that you can hang up somewhere and register each animal when it passes. The best solution for a good research if you ask me! I often check the environment for traces of animals. Knowledge and information are the keys to success.
If I install my camera somewhere I always put a game camera next to it, because I can then observe the behavior of the subject. This gives me new information to adjust the setup or change my settings.
When setting up a camera trap you can often determine the setting yourself in the area. Look carefully at beautiful perches, moss spots or other beautiful pieces of nature. your creativity can sometimes be your biggest limitation. In addition to looking at beautiful pieces of nature, you can also look at new perspectives. Be innovative and try to make something you have never seen anywhere before.
even though I can tell you a lot more about this, I hope you learned something from my article and enjoyed some of my pictures. If you have questions about this subject or are interested in a workshop, you can always contact me.
